I have setup ddns with afraid.org and created a config on my router to update it. However I appear to of missed a stop. I copied the link into a computer on a different ip address and got my ddns record changed. My router though did not ever get the ddns record updated. I left it up for 6 hours before finally changing it back manually. Can someone see if they can spot my error?
Thank you!

Why don't you use ip ddns command ?
Look this: http://www.firewall.cx/cisco-technical-knowledgebase/cisco-routers/811-cisco-router-ddns.html

it fails to update when i try the ip ddns command. I've read online that you need to use a ip sla command for afraid.org ddns.
when I run the debug command I get
Router#

If I setup the ddns update way you are talking about here is the error i get on the dubug mode

I've noticed I can't ping from the router to the internet, however the internet works fine all on workstations. I did add on each acl at the bottom permit icmp any any and that didn't seem to fix it so I took it off. I also notice on the debug mode for ddns update that it shows the url it's trying to connect to but it's missing the "?" that goes between the .php and the Y that you can see in my debug log shown above.
